Whats wrong with openssl ?

openssl des3 -in test.txt -out test.txt.enc

or

openssl aes-256-cbc -in test.txt -out test.txt.enc

This is only as strong as your passphrase.  Using something like GPG has 
other advantages since the private key can be kept in a separate location 
from the encrypted file.
